Abstract:The Federal Highway Administration, U.S. Department of Transportation, has established a Road Weather Management Program (RWMP) that seeks to improve the safety, mobility and productivity of the nation’s surface transportation modes by integrating meteorology into transportation operations and maintenance. A central activity of the RWMP has been to develop and encourage the deployment of tools to support decision making by transportation operations and maintenance. One of those tools is the Maintenance Decision Support System (MDSS) that offers road maintenance managers guidance regarding efficient tactical deployment of road crews, equipment and materials with the expectation that the MDSS can save state and local Departments of Transportation money and time while also enhancing the safety and mobility of the traveling public. This report presents the results of a Benefit-Cost Assessment (BCA) of the use of an MDSS by the City and County of Denver, Colorado. The MDSS was used over two consecutive winters (2007-2009) and resulted in budget savings that exceeded costs of the system while maintaining the level of service on the road network. Most of those savings are attributable to more effective tactical crew deployment decisions. The nature of the small sized snow events and the local and arterial road system of the City of Denver resulted in limited ability to test the effects of the MDSS treatment module. Overall, the City and County of Denver management and staff were very satisfied with the utility and performance of the MDSS in supporting their maintenance decisions.
